What is PhenAprin

An appetite suppressant that is said to boost your metabolism and trigger extreme Hyper-Metabolizing function – ideal for burning fat.

PhenAprin is a diet pill that’s marketed as an “advanced formula” weight loss aid. It’s made in the USA by SutraHealth.

With a name like PhenAprin, it’s pretty clear SutraHealth is targeting people who are looking for an alternative to Phentermine. The company never mentions the popular prescription-only weight loss medication in the marketing material but, like Phentermine, PhenAprin is a white tablet with blue specks.

With such a distinctive design, and a similar name, there’s no denying what this product is meant to be but there are plenty of Phentermine substitutes and PhenAprin is not one of the best.

Phentermine is an appetite suppressant some people can get on prescription. It’s chemically similar to amphetamine and poses a threat of addiction so there’s a lot of red tape regarding its distribution.

Phentermine also has the potential to cause side effects, some of them quite dangerous. That’s one of the reasons why some people who can get a prescription go looking for a safer alternative to use instead.

PhenAprin Weight Loss Benefits

SutraHealth claims PhenAprin users can expect six key benefits:

  • Decrease appetite
  • Boost metabolism
  • Stimulate thermogenesis
  • Burn excess body fat
  • Accelerate weight loss
  • Increase energy

How Does PhenAprin Work?

Like Phentermine, PhenAprin is designed to suppress appetite. It allegedly offers some additional benefits as well. That’s not unusual. Most Phentermine substitutes aim to do the same.

If PhenAprin can mimic Phentermine’s ability to control appetite, it will take a lot of the misery out of dieting by helping you to eat less without feeling hungry.

If it can boost metabolism and thermogenesis, it will increase daily energy expenditure, helping you to burn extra calories.

Diets work by causing the body to experience an energy shortage that forces it to begin burning fat. A good appetite suppressant makes it easier to maintain and sustain the required low-energy state.

Diet pills that boost metabolism and thermogenesis, enhance the energy shortage caused by diet, increasing the need to burn fat. This helps you to lose weight faster.

When your body is short of energy, it causes fatigue. Most Phentermine substitutes address this by providing stimulants. PhenAprin appears to do the same.

There’s nothing wrong with stimulants. Although a minority of people have to avoid them, most people find them beneficial.

However, overusing stimulants greatly increases the chance of side effects so diet pill manufacturers have to walk a very thin line.

PhenAprin Usage Guidelines

The dose is two tablets per day. You take the first tablet 30 minutes before breakfast and the second one 30 minutes before lunch.

A warning on the back of the bottle points out the wisdom of seeking a physician’s advice before taking supplements. This particular supplement has a reputation for causing side effects so we have to echo that advice.

Ingredient Profile

Each tablet provides 540 mg of a proprietary blend.

The PhenAprin proprietary blend consists of undisclosed quantities of the following six ingredients:

  • L-Phenylalanine
  • Caffeine Anhydrous
  • Theobromine
  • L-Taurine
  • L-Carnitine
  • DHEA

Ingredient Potential

The most noticeable thing about the PhenAprin diet pill formulation is the lack of appetite-suppressing ingredients. That’s a big failing for a product that aims to replicate the abilities of the most famous appetite-suppressing medication in the world.

PhenAprin also lacks metabolism boosters. Caffeine can boost metabolism but, in this formulation, it’s pretty much going it alone.

This makes the lack of inclusion rates particularly worrying because there is no way to know if the formulation compensates for the lack of good companion ingredients by providing an overly sizeable dose of caffeine.


L-Phenylalanine is an amino acid. You can get it from many dietary proteins including meat, eggs, and fish.

In addition to being necessary for muscle growth, L-Phenylalanine also serves other roles in the body. One of the things it does is support the production of dopamine.

Dopamine is a brain hormone that affects mood.

Although researchers are exploring the value of L-Phenylalanine as a possible treatment for depression and several other conditions, its potential in most areas is still unknown.

Caffeine Anhydrous

Caffeine is a versatile stimulant. It fights fatigue, clears the mind, and improves mental focus.

Research shows caffeine supports fat loss as well. It achieves this by increasing metabolism and thermogenesis (

Caffeine is an incredibly popular diet pill ingredient but some manufacturers abuse it by using too much. This increases the risk of side effects such as headaches, nausea, racing heartbeat, and jitters.


Theobromine is a compound present in some plants. Cocoa beans are a particularly good source.

Like caffeine, theobromine stimulates the central nervous system but it’s less likely to interfere with sleep.


L-Taurine is an amino acid that serves multiple roles in the body. It’s a key ingredient in energy drinks and is also present in many sports supplements.

However, although some research suggests taurine may improve physical performance experts say its value in this area requires further study. (


L-Carnitine is an amino acid-like chemical that helps the body use fat for energy. It also supports heart and brain function along with several other biological processes.

There are plenty of arguments for taking L-Carnitine in supplements but there are some negatives as well.

L-Carnitine side effects may include nausea, diarrhea, and fishy-smelling body odor and breath.


DHEA (Dehydroepiandrosterone) is a hormone your body produces in the adrenal glands. As is often the case with hormones, production rates can decrease with age.

The DHEA in supplements is a synthetic version. It’s often produced using yam extracts.

Supplement manufacturers sometimes use DHEA to support weight loss. The ingredient is also present in some supplements that aim to tackle other issues such as depression, osteoporosis, and erectile dysfunction.

Unfortunately, study results are contradictory and there is not enough evidence to support using DHEA in any of these areas.

However, DHEA is associated with several side effects including headaches, fatigue, and mood changes. There may also be interaction issues when it’s used alongside certain medications. (

PhenAprin Customer Feedback

There’s plenty of customer feedback for this product. Some of it is good but there are also plenty of negative reviews.

Several customers say SutraHealth offers customers free products and discounts for leaving a review. If this is the case, it casts doubt on the integrity of the five-star ratings.

Known Side Effects

Many customer reviews mention side effects and an alarming number of people say using the pills pushed up their blood pressure.

There are also a surprising number of reports of increases in appetite.

Some of the other side effects PheAprin users are reporting include:

  • Headaches
  • Bad breath
  • Acid reflux
  • Nausea/vomiting
  • Irritability
  • Anger
  • Mood swings
  • Depression
  • Dizziness
  • Stomach pain
  • Pain in the arms and legs
  • Chest pain
  • Palpitations
  • Fatigue

Several customers who claim to have prior experience of the prescription drug claim PhenAprin causes worse side effects than Phentermine.

PhenAprin Purchasing Options and Considerations

SutraHealth mainly markets its products via Amazon but the company website shows signs that this may change in the future.

At the moment, all its products have a sales page on the site, along with “buy now” buttons. The buttons link to further sales pages that have buttons that link to Amazon.

The present setup suggests SutraHealth may be prepping the site to become a fully functioning online store.

At the time of this review, a 30-day supply of PhenAprin cost $38.95.


PhenAprin does not have a money-back guarantee. Some of the best Phentermine alternatives do. This alone places the product at a serious disadvantage in such a competitive market.

PhenAprin Review Conclusion

SutraHealth says PhenAprin is a pharmaceutical-grade diet pill that provides a powerful combination of natural ingredients that enter the blood quickly to suppress hunger and stimulate metabolism.

It will also allegedly make you feel so energetic and full you won’t be able to eat for hours.

Furthermore, it will do these things without causing jitters like other diet pills do.

Remember, these are the claims being made by the manufacturer. It’s marketing spiel. The SutraHealth website also makes some claims that are not on the bottle. Namely that the supplement elevates the mood.

Many of the claims made by SutraHealth are at odds with the claims being made in customer reviews.

Instead of reducing appetite, PhenAprin appears to make some people more hungry.

Instead of elevating the mood, it could cause depression and other negative emotions. A lot seems to have gone wrong somewhere along the line.

PhenAprin is a supplement that aims to capture the attention of people looking for a Phentermine substitute but a lot of customer reviews say it’s a poor alternative that lacks potency.

There are plenty of Phentermine alternatives to choose from. PhenAprin is not one of the best.

The top Phentermine substitutes have more credible ingredients and better customer feedback. They also have money-back guarantees. If you want a good diet pill like Phentermine, we suggest you choose one of them instead.
